Adjustable rotation base

Abstract

An adjustable rotation base includes a base housing and a transportation arrangement. The base housing has a bottom side, an upper side for coupling with the supporting post to support the outer umbrella in an upright manner, and a receiving cavity indently formed on the bottom side of the base housing, wherein the base housing includes a stationary unit provided at the bottom side for sitting on the ground surface in a stationary manner, and a plurality of transferring wheels rotatably supported at the bottom side of the base housing. The transportation arrangement is provided at the base housing to operate the base housing between an idle mode and a transportation mode in which the stationary unit is upwardly lifted to allow the transferring wheels being sitting on the ground surface, such that the base housing is adapted to be transported on the ground surface via the transferring wheels.

What is claimed is: 
     
       1. An outdoor umbrella, comprising:
 an awning frame; 
 a supporting shaft supporting said awning frame; and 
 an adjustable rotation base, which comprises: 
 a base housing arranged to couple with said supporting shaft to support said awning frame in an upright manner, wherein said base housing comprises a plurality of bodies detachably coupled with each other to form said base housing, wherein each of said bodies has a filler cavity for filling with mass medium; and 
 a plurality of transportation wheels rotatably provided at said bottom side of said base housing so as to facilitate easy transportation of said adjustable rotation base, wherein each of said bodies has a receiving cavity, wherein when said bodies are coupled with each other, said receiving cavities of said bodies form a support cavity, wherein said supporting shaft is detachably received at said support cavity to support said awning frame, wherein each of said bodies has an engagement tooth and an engagement slot, wherein when said bodies are coupled with each other, said engagement tooth of one of said bodies is engaged with said engaging slot of adjacent body, wherein said adjustable rotation base further comprises a base frame which comprises a plurality of frame members connected with each other to form a secure frame structure for accommodating said bodies, wherein each of said frame members has an elongated mid portion and two elongated side portions to define a frame platform, wherein each of said bodies further has an elongated engaging slot indently formed at said bottom side of said body, wherein said frame members are extended to bias against said bottom sides of said bodies in a vicinity of said engaging slots. 
 
     
     
       2. The outdoor umbrella, as recited in  claim 1 , wherein said adjustable rotation base further comprises a plurality of connectors fastening said frame members to said bodies at said engaging slots. 
     
     
       3. The outdoor umbrella, as recited in  claim 2 , wherein said frame members are coupled in a “X” structure, wherein one of said frame members has a through slot formed thereat, wherein another said frame member passes through said through slot to form said “X” structure.
